Trait Credentials 

pub trait Credentials:
    Send
    + Sync
    + Debug {
    // Required method
    fn token(&self) -> TokenFuture<'_>;
}

Credentials supply the access token each call is sent with. Send + Sync on every target, so a client can live in a UI framework’s reactive state (Leptos 0.8 keeps memo values Send + Sync even in a browser); only the future token returns is !Send there.

Required Methods

fn token(&self) -> TokenFuture<'_>

A valid access token.
